The TeAm needs help on this project!

I would like to encourage people that are looking for a new project to run to check out Folding@Home.

Folding@Home is a mature project run by dedicated scientists at Stanford University. It will be around for a long time, they have plans in place for when the CPU count increases up to one million (currently 200,000).

F@H is through the phase of perfecting their software and is truly "NOW" sending WUs that are working to find cures to many diseases. You can see the diseases you could be helping to find cures for HERE.

They have many published papers about their research, a result of work that has been done by us crunchers. You can see that results of our contribution are freely shared by this non-profit organization.

Even though they have finished the long phase of perfecting their software they continue to find and test new technology to advance their research faster, a cure cannot be found fast enough for them.

These new technologies have led to some misunderstandings and problems.
For one thing, they use more resources than really should be used by a DC client. They solved this by making them voluntary, the client has to be configured to recieve them.

Another problem - how to entice folders to do them if they use more resources? Give bonus points for these WUs that do more science! This was recieved pretty well except that these are only a small percent of all WUs and there are not enough to go around. (We can randomly get them.)

With one new technology - QMD - that really speeded up the process, they had to make a decision. Because this new technology needed to use some licensed libraries they had to decide which compiler to use, for AMD or Intel processors. They looked at which processor type was the largest percent of all folding processors - Intel P4/Xeon. They also looked at which complier's libraries ran the WU the fastest - the Intel libraries.

Stanford recommends that these WUs only be run on dedicated machines. There are not many people that choose to run these WUs because they use so much memory bandwidth and ram (300MB for a short while at the beginning and then 200MB the rest of the time). In fact they are less than 1% of all WUs.

They say they benchmark them like all other bonus WUs, but they get more points per day. This has led to some hard feelings from Mac and AMD owners (AMDs do best on all other WUs).

Stanford has not been able to solve this problem yet - it is really an Intel/AMD not sharing their technology with each other problem.

The scientists desire to find cures takes precedent over hard feelings by some participants and so the testing of this new technology continues.

Thanks for considering Folding@Home for your next project.

This TeAm really should be ranked higher than 25 in this great project 🙂

EDIT: spelling 😕
 
a bump and a :beer: for a fine project 🙂

thanks for all the info GleeM, you do a great job for F@H. :thumbsup:
 
A second thought: why not join the HSR - Holiday Season Race - on TAS' side? A lot of fun and excitement (the mini teams switch the lead every second day - more or less - and the project thrives! Check the HSR-thread! 😀

Atm I have & will have other DC commitments for a little while ,though I will dip into this one in the future 😉
Anyway for right now I have a friend who has 4 PCs (AMD ~2GHz Skt A rigs AFAIK) ,currently he doesn't run any DC projects despite my attempts😛
F@H might be one he'd go for, but he's virtually paranoid about not wanting to help any of those 'big profit making drug companies'.
If you could show us some info regarding your statement, You can see that results of our contribution are freely shared by this non-profit organization. ,then I think that would go a long way to turning him over to the 'dark side' 😉😀

Also ,how much RAM does F@H use ? (excluding those special WUs)

Btw I'd be surprised if TA F@H didn't gain a fair few people after S@H1 ends 😉

[edit]I've just sent him an email asking his reasons for & against him running a DC project 😉 ,as well as seeing what he's upto tomorrow night😛)

Thanks for the encouragement and efforts Assimilator1 :thumbsup:

With the "Published Papers" link, I was trying to show that Folding@Home shares their research results.

But I found the following in the F@H FAQ page:
Who "owns" the results? What will happen to them? Unlike other distributed computing projects, Folding@home is run by an academic institution (specifically the Pande Group, at Stanford University's Chemistry Department), which is a nonprofit institution dedicated to science research and education. We will not sell the data or make any money off of it.

Moreover, we will make the data available for others to use. In particular, the results from Folding@home will be made available on several levels. Most importantly, analysis of the simulations will be submitted to scientific journals for publication, and these journal articles will be posted on the web page after publication. Next, after publication of these scientific articles which analyze the data, the raw data of the folding runs will be available for everyone, including other researchers, here on this web site.

I've been doing those QMDs for so long that I'm not sure how much ram a regular WU uses. I think 20-40 MB.

Any folders out there that can answer this with a more sure answer?

Thanks
 
The WU I am folding now is using 106MB of RAM, but you don't have to commit that much if you don't want to. (I told the config. that it was OK to accept large work units.)

With my configuration (no QMDs) I see the memory usage range from as low as ~5M to as high as the one I'm doing now.

(F@H has never seemed to interfere with anything else I try to do on the computer.)

edit: this WU is P1150

Thanks Insidious 🙂

P1150 is a bonus WU and uses lots of ram.

So 5MB is the low end. What would be the high end for a regular WU?

Oops, almost forgot: The newest client can be configured so that you can tell the Assignment Server how much ram it is OK for F@H to use :thumbsup:
 
I think your 20-40MB estimate was about right.

I'm doing a couple projects at once right now, and it has distracted me.. I don't watch so closely as I used to. 😕

yeah i have 3 machines right now w/ the 100 meg WU's 🙂


definately great read Gleem!

i really wish i would have gotten into this earlier. I just started less than two weeks ago. I also graduated college this last summer and finally landed myself a really good job 🙂 So as a present to me I went out and bought about 800-900 dollars worth of computer stuff for 6 news machines i'll hopefully have up an a week or two 🙂


also guys is really easy to get extra processors on your side... family friends.... most of them when you tell them what the program is for, they're all for it... currently, only 4 out of the 9 procs i have which reported in so far are my own 🙂
 
Those new 23XX series WUs (some go up to 1254 Pts :Q ) gank some ram too. Dual Core@ 2.6= 600+ on the 114X series. 🙂 1476s are also nice (364 pts, about 22 hrs on a 2.6 GHz AMD64)
 
Hey, Glee, or anyone else who knows the answers,

Couple of questions:
1) I have a ton of memory on my machine (5GB) to run very large compiles or interpreters, and they are not in use majority of the time. Is there any setting that allow me to get projects which uses large amounts of RAM, so that I would feel that my machine is being put to good use?

2) Do AMD machines, specifically Opterons ever get QMD's, or would they only give those to Netburst machines?

Thanks
--HB
 
Only Genuine Intel machines are assigned QMD work units. F@H will not allow any other platform to process these.

You can tell the configuration it is OK to receive large work units, but you can not specify that is all you want.

You can try running several instances of F@H with the flag to do big work units turned on.
 
Cool! Just checked and thought my RAM usage was high: peak 125MB, avg 109MB. Then I checked out the project: 1140, and found out I'm sitting on a 600 pointer 😀.

My one server that I have folding (so far) only has a little 166 pointer using less than 10MB, and an older Win2K box has a 241 pointer that's using around 60MB.
 
Thanks, Insidius, and trvinom,

I guess F@H is not fully compatible with AMD machines after all. Would it be a better use of resources for the opteron rig in my sig to be doing Rosetta instead; or would it matter?

This is not entirely true....
If you are running linux, You can pick up QMD's with AMD processors.

F@H cannot prevent you from moving a QMD WU to your AMD computer. It will run and finish, just not as fast as on Intel.

Intel and AMD both make their products so that only their own hardware/software combination will run the fastest.

(AMDs do best on all other WUs).

I had thought about taking a different angle with this thread.

Something like:
1. How much can a research DC project experiment with better ways of finding cures faster (which is ultimately the reason we do this stuff)?

2. Would it be OK for them to test (on volunteers) some new technology that would use more resources than older computers could easily handle?

3. Would it be OK for them to entice volunteers with more points to help them test this new technology?

4. Would it be OK for them to test some new technology that would only run on one platform during that test?

5. Or should they just continue with what they started with? And/Or start a new DC project when new technology comes out?

Thanks 🙂
 
Thanks, Xbass and Glee,

that sounds great, I guess I will keep doing it on Linux, seems to work better at folding than on Win XP. I'm running two instances right now, one with -adv flag, the other without. I will see which ends up being better.
 
Gleem
My mate gave me a tepid response response about doing any DC ,though he seemed slightly more interested in F@H than any other I've mentioned to him.
He may warm up to it in the future but don't hold your breath.

Sorry I couldn't recruite him ,maybe in the future he might join but who knows.....he's a tricky quirky ah heck! 😉
